Scientific Reports, 2022 In this study, we tested the hypotheses that (i) rate of force development (RFD) is correlated to muscle architecture and dynamics and that (ii) force–length–velocity properties limit knee extensor RFD.

Ultrasound-derived Biceps Femoris Long Head Fascicle Length: Extrapolation Pitfalls [PDF]
Medicine & Science in Sports & Exercise, 2019 ABSTRACT Purpose This study aimed to compare biceps femoris long head (BFlh) fascicle length (Lf) obtained with different ultrasound-based approaches: 1) single ultrasound images and linear Lf extrapolation, 2) single ultrasound images and one of two different trigonometric equations (termed equations A and B), and 3)

Sports Medicine - Open, 2023 Background Long-term stretching of human skeletal muscles increases joint range of motion through altered stretch perception and decreased resistance to stretch. There is also some evidence that stretching induces changes in muscle morphology.

Comparison of calf muscle architecture between Asian children with spastic cerebral palsy and typically developing peers. [PDF]
PLoS ONE, 2018 To compare the muscle thickness, fascicle length, and pennation angle of the gastrocnemius, soleus, and tibialis anterior between Asian children with spastic cerebral palsy (CP) and typically developing (TD) peers.This cross-sectional study involved a ...

Endoneural selective stimulating using wire-microelectrode arrays [PDF]
, 1999 In acute experiments eight 5- to 24-wire-microelectrode arrays were inserted into the common peroneal nerve of the rat, to investigate whether the electrodes could selectively stimulate motor units of the extensor digitorum longus (EDL) muscle.

Three-dimensional architecture of the whole human soleus muscle in vivo [PDF]
PeerJ, 2018 Background Most data on the architecture of the human soleus muscle have been obtained from cadaveric dissection or two-dimensional ultrasound imaging. We present the first comprehensive, quantitative study on the three-dimensional anatomy of the human ...

Muscle spindles in human tibialis anterior encode muscle fascicle length changes.
J Neurophysiol, 2017 Muscle spindles provide exquisitely sensitive proprioceptive information regarding joint position and movement. Through passively driven length changes in the muscle-tendon unit (MTU), muscle spindles detect joint rotations because of their in-parallel mechanical linkage to muscle fascicles.
